Antennas
Configuration of external antennas
On this page, you configure the settings for the connected external antennas.
Note
50 Ω terminating resistor
Each WLAN interface has four antenna connectors. Connectors that are not used must have
a 50 Ω terminating resistor fitted.
An antenna must always be connected to the antenna connectors R1 A1 and R2 A1 as soon
as the WLAN interface is switched on. If no antenna is connected, the relevant interface must
also be disabled for Rx and Tx. Otherwise, there may be transmission disruptions.
